How the Film Slitting Process Works: Precision and Customisation
Precise film slitting is a key stage in packaging production, directly impacting filling efficiency, the quality of the final product, and the minimisation of manufacturing waste. The accuracy of this process determines the appeal of the packaging, its functionality, and the cost-effectiveness of its use.
What is Film Slitting and Why Is It Necessary?
Film slitting is a technological process in which a large roll of material (jumbo roll) is cut into narrower strips with precisely defined width, length, and roll diameter. This ensures convenient use on filling machines, optimises packaging line performance, and guarantees a high level of automation and accuracy during the filling process.
What Types of Films Can Be Slit at Artha-S?
The equipment at Artha-S enables the slitting of various types of films, including:
- BOPP (biaxially oriented polypropylene): transparent, pearl, or metallised
- CPP, PE (LDPE, HDPE): for heat sealing and lamination
- Single-layer and multi-layer films
Artha-S’s Technical Capabilities in Film Slitting
Artha-S uses advanced slitter rewinders BJK-K1300 (Taiwan) and KAMF, offering the following parameters:
- Film width: from 120 mm to 1200 mm
- Film thickness: from 15 to 100 microns
- Maximum number of lanes: up to 10
- Minimum lane width: 40 mm
- Rewinding onto cores with a specified roll length
- Edge alignment control, constant tension monitoring, and symmetry checks
What the Process Looks Like in Practice
- A large film roll (jumbo roll) is mounted on the slitter rewinder.
- Required settings are applied (width, number of lanes).
- The film moves through the machine under constant tension control, ensuring cutting precision and quality.
- The film is automatically divided into narrow rolls.
- Finished rolls are wound onto cores, labelled, and prepared for shipment.
